Heya,
I'm working through
http://www.ros.org/wiki/motion_planning_environment/Tutorials/Tutorial%20Aand
when I attempt to launch the PR2 in Gazebo, I get the following error.

/opt/ros/cturtle/stacks/simulator_gazebo/gazebo/gazebo-svn/server/controllers/ControllerFactory.cc:99
: Exception: Failed to load libgazebo_ros_prosilica.so:
libgazebo_ros_prosilica.so: cannot open shared object file: No such file or
directory

I couldn't find how to build the object or where to find it. Any ideas?

Please and thank you,
-David!!
